Disclosed are an airboat and a processing method therefor. The bottom of the airboat is made of aluminum alloy, and is provided with a drag-reducing coating. An epoxy putty coating, an epoxy resin coating and an elastic coating are also arranged in sequence from the inside to the outside between an aluminum alloy plate of the bottom of the boat and the drag-reducing coating. In the airboat of the present invention, a polyurea material is first used to make a strain layer, and the drag-reducing coating is arranged on the strain layer, which not only prevents the drag-reducing coating from falling off, but also reduces the resistance of the drag-reducing coating.

Disclosed are an airboat and a manufacturing method therefor. A hull is divided into a front cabin and a rear cabin; both left and right sides of the rear cabin are provided with side decks; a front cabin sealing plate at the rear of the front cabin separates the front cabin and the rear cabin; an integral buoyancy body is provided on the inner bottom and the side wall of the rear cabin; the buoyancy body is covered by a plurality of sealing plate strips arranged from front to back; the sealing plate strips constitute a sealing plate; the sealing plate, the front cabin sealing plate, a rear cabin tail plate, and the side decks are sealed to form an accommodating cavity of the buoyancy body. In the airboat of the present invention, by means of an open box type spraying method, the buoyancy body is fully filled between a bottom plate of the hull and a U-shaped inner deck, thereby improving the cabin bearing capacity.

Abrégé

A twin-engine twin-propeller airboat, comprising a boat body (1), an engine system (2), a speed reducer set, a propeller system (3), a steering system (4), and a control system. An upper deck of the boat body (1) tilts forward, with a lower front end and a higher rear end. The engine system (2) is located at the 1/3 position at the rear of the boat body (1) and comprises two engines (21). The engine system (2) is connected to the propeller system (3) by means of the speed reducer set, so that the engine system drives the propeller system (3). The steering system (4) is a rudder (14) vertically disposed at the stern. The rudder (14) is connected to a handle or a steering wheel in the control system by means of a handle control and assisting device. After the boat body (1) is launched, the deck is naturally in a horizontal state, and the axis of a driving shaft (10) of the propeller system (3) is parallel to the horizontal plane. The airboat is widely applicable, and has a traveling capability that common watercrafts lack, in addition to all the functions and capabilities of ordinary assault boats and small yachts.
